Parishii. The plant is also much freer in growth and more floriferous, 
The lip is larger and has a broader white band round it. Especially is this 
the case in one of the forms which Reichenbach calls D. polyphlcebium 
var. Emericii. D. polyphleebium was found by me on four different 
occasions growing with D. Pierardii. 
No doubt the flowers of D. rhodopterygium and D. polyphlcebium are 
very similar, and the view generally accepted is that they are both natural 
hybrids between D. Pierardii and D. Parishii. As so many hybrids are now 
making their appearance in England, it is to be hoped that this surmise 
will soon be capable of proof. 
The same remarks regarding the effect of hot and dry plains on 
members of this group are equally applicable to D. cretaceum, D 
primulinum, and D. crepidatum. 
The. variety of D. cretaceum found in the neighbouskail of Raa 
is miserable, and not worth growing, but if the plants be collected. in the 
valleys of the low- -lying hills some eighty miles distant, they. will be 
charming, and good enough to please any one. By far the most beautiful 
variety of this plant is found in the Andaman Islands, where, in const 
quence of the great rainfall, the plant grows with great. luxuriance, and 
bears an abundance of flowers. This Andaman variety is also delicious 
sweet-scented. 
D. primulinum giganteum, the mountain form of D. primolinum, i 
unquestionably the best, having broad sepals and petals, the great objection 
to the common form being the great narrowness of these parts se: 
flower. 
D. crepidatum of Rangoon is absolutely worthless. The flowers a 
this plant do not open properly, but form numerous seed-pods, and. as far a 
my judgment. goes are self-fertilising. The form which grows in the hills 
is a pretty thing and free flowering. 
There are probably good varieties and bad varieties of all Orchids; 
it seems clear, however, that the best varieties are found where there is 
the shortest season of drought and where plants are sheltered from hot, 
drying winds.
